C. Hough, OE feolheard and OE irenheard: Two hapax legomena reconsidered (Old English literature, 'Battle of Maldon'), NEOPHILOLOG, 84(1), 2000, pp. 127-136
The unique compound feolheard in The Battle of Maldon line 108b has been va
riously interpreted as 'hardened by the file' or 'as hard as a file.' The f
ormer would correspond to a well-evidenced pattern of word-formation in Old
English, whereas the latter would represent a type unparalleled in the kno
wn corpus. Comparison with other Old English compounds in -heard strongly s
upports the interpretation 'hardened by the file,' and also suggests that t
he unique compound irenheard in Beowulf line 112a should be taken to mean n
ot 'as hard as iron' but 'hardened by the sword.'
